Here a lung-on-a-chip device was developed and fabricated using 3D-printing of molds. The lung-on-a-chip device was used as a lung injury model by overstretching of murine lung epithelial cells (MLE-12) monolayers, resembling the injury during mechanical ventilation. The cells were exposed to 25% strain, representing pathological conditions seen in ventilator induced lung injury of patients with

Insekter är en essentiell komponent i många ekosystem. Rollerna som de har är viktiga, vilka inkluderar spridning av växters frön, pollinering och att vara en källa till näring för andra djur. Dock finns aspekter med insekter som innebär hot för människor. Exempelvis kräver malaria cirka 400 000 människoliv per år, en sjukdom som förs vidare av myggor. För att kunna bekämpa sjukdomar som malaria Using laser it is possible to measure the backscattered light from insects. The resulting signal can then be analysed in order to potentially determine the species of the insect. Estimating the fundamental wing beat frequency (FWBF) of insects is important in order do this classification of species, which is an area of research that has been explored previously. In this thesis, the relative phase

In this study, the extraction and isolation of xylan from milled oat hull materials was investigated. Alkali extraction by 2 M sodium hydroxide at 40°C overnight was applied. The yield of extracted xylan was 5%. The extracted xylan was isolated from the extraction mixture by ethanol (99.9%) after neutralization and its purity was checked, resulting in a66% pure product. The semi-purified xylan was

For a city and culture that excels at adding value to waste, Kisumu struggles with a systematic approach for solid-waste management. Food and animal wastes run rampant in the streets while families still cook for hoursevery day using harmful fuels like kerosene, charcoal and firewood. This project takes to heart the insight that if a solution isn’t affordable to those who need it the most — it’s n

Momentvektorering uppnås genom att manipulera bilens hjulhastigheter, i syfte att öka kurvhastigheterna och förbättra trafiksäkerheten. En dubbelkoppling på bakaxeln är en möjlig vektoreringsmetod för en bakhjulsdriven Formula Student-bil. Dubbelkopplingen gör att det inre hjulet kan glida och därmed skapa ett vridmoment kring bilens kropp i kurvans färdriktning. Målet med examensarbetet var att Torque vectoring for automobiles is used to increase cornering speeds and improve road safety by manipulating the car's wheel-speeds. One method of torque vectoring for a rear-wheel-drive Formula Student race car is using a dual-clutch to slip the inner wheel thus create a yaw moment during cornering. The goal of this thesis was to develop and design an electronic control unit to automaticall

This essay follows the repatriation process and debate concerning the return of the Paracas textiles from the Museum of World Culture in Gothenburg, Sweden to the National Museum in Lima, Peru. The essay uses mass media such as newspaper articles and radio segments to map the themes and problems that arise when one country asks for the return of cultural artefacts and the other country has to resp

Vår värld blir alltmer digital samtidigt som kunder blir alltmer kräsna. Mjukvaruföretag idag jobbar agilt och kämpar för att fokusera på kundvärde i en konkurrensintensiv bransch. Detta examensarbete presenterar aktiviteter som är viktiga för att effektivt samla in och integrera kundåterkoppling i SaaS-företag som arbetar B2B. Nuvarande företagsprocesser har kartlagts och analyserats utifrån exisEven though companies are aiming for an agile way of working, and by that mainly focusing on providing value to their customers, it is challenging to get accurate customer data. Software companies are struggling in effectively and efficiently integrating customer feedback in their development processes. The purpose of the study was therefore to describe and understand structured approaches whose p

The present master thesis was performed in cooperation with the company “Aventure AB”. The company’s R&D department envisioned a new yoghurt-based product able to decrease the blood glucose levels after a meal. The innovative characteristic of the product is due to the diet fibers of the barley grain, which is going to be incorporated inside the yoghurt. The preliminary experiments which were

“Cultural identity is closely linked to their ancestral lands. If they are deprived of them, by means of forced displacement, it seriously affects their cultural identity, and finally, their very right to life lato sensu...” (Sawhoyamaxa Indigenous Community v. Paraguay) In the last five decades a movement calling for the protection of indigenous peoples’ rights has precipitated in a wave of inte

In vehicles there are many issues involving the safety and performance. The safety issues are often regulated by governments, whereas the performance by the customer. One solution to both these issues is to take use of an all-wheel drive system, where a coupling engages and disengages driving axles when needed. Such a solution will, through added traction and stability, increase performance and sa

Studien ska visa eventuell skillnad i BHAR, 3 år - för börsintroduktioner på den nordiska marknaden med hänsyn till det relativa innehavet av tillgångsslag.

Previous research on which this study is based, studies long-run performance in other markets than the Nordic. In addition, it has focused on drawing conclusions about other explanatory variables. The study is based on a sample of a total of 213

På den ryske botanikern Mikhail Semyonovich Tsvets gravsten står det "Han uppfann kromatografin, separerade molekyler men förenade folk". Hans metod för att separera molekyler används än idag - till exempel i detta arbete. Tsvets försöksuppställning bestod av en glascylinder fylld med kolsyrad kalk, samt en lösning som innehöll olika färgpigment från växter. En stund efter att han hälltAdenosine tetraphosphate, or Ap4A, is a nucleotide with very interesting proposed biological effects. Previous studies have indicated that blood glucose levels in mammals might increase in the presence of Ap4A, and that Ap4A might antagonize pancreatic ATP channels. In order to study these effects further, a reliable method of separating Ap4A from other nucleotides in biological samples is require

Method: This is a basic case study that focuses on the pharmaceutical company AstraZeneca. It has an idiographic approach, and several semi-structured interviews have taken place. Pattern-

Våra sinnen skärps när vi omger oss bland grönska, djur och inte minst de olika årstidernas påverkan av upplevelsen i naturen. Att vistas i skog och mark har stor betydelse för människors hälsa och livskvalitet. I detta arbete har jag konstnärligt undersökt ett synliggörande av ett idag undangömt kulturlandskap sydväst om Kalmar. Ett område innehållande unika och höga naturupplevelsevärden där jaAll our senses sharpen when we surround ourselves with greenery and animals. The seasons does also affect the experience among ora, fauna, light and warmth. Just to be in nature has a big impact on people’s health and life quality. In this project I have examined how to with artistic means make a hidden cultural landscape, southeast of Kalmar, visible. This with constructing unique and fine natur

Bakgrund: Stressrelaterad ohälsa är i dagsläget en vanlig följdkonsekvens av att vardagen blir svårhanterlig.

Objective: The aim of the study was that from an occupational therapy perspective identify the usefulness of yoga as an inter

Urban Sprawl is one of the challenges to urban development in many nations. Different aspects of the phenomenon have been researched with a view to providing solutions to myriad of ills attributed to it. For any meaningful intervention, however, assessment of development to ascertain sprawl is essential. Despite this, its quantification and monitoring in environment with paucity of data remains a

Lera har vi alla kommit i kontakt med på ett eller annat sätt, men det vi kanske inte vetat om är att lera har flera fantastiska egenskaper som gör att det kan användas i många olika applikationer. De som sysslat med keramik är bekanta med att lera blir mjukt och formbart när det är blandat med vatten, men kan sedan hårdna när det värms och torkas, och då behålla den form den formats till. Det är dClays are negatively charged nanoplatelets with a layered silicate structure. It has been observed from small angle X-ray scattering measurements, and coarse-grained molecular dynamics simulations (CG-MD) that clay nanoplatelets are able to form stacks, known as tactoids, in the presence of divalent or multivalent counterions [8, 5]. In this thesis, the interactions between clay nanoplatelets and

The aim of this essay is to investigate if the Judas figure in the Gospel of Mark was a betrayer or a servant, who only wanted to fulfill Jesus’ will, by discussing the significance of παραδίδωμι in these texts, and in relation to Isaiah 53. The question is: in what way is the Judas figure in the Gospel of Mark shaped by the verb παραδίδωμι in Isaiah 53:6 and 53:12 according to LXX (the Septuagint
